Wonderful bowling game, I don't think I've seen anything like it on the portal before hand. The art and cinematics were all quite well done, I'm a huge pixel art fan, so you hit me in a soft spot.
The bowling controls were a bit tough to get used to, but once you got it, it ended up working quite nicely. I do wish that it didn't show the controls the entire game if you're one player though, it was a little annoying, and the fact that the other players had the same sprites was disappointing, but understandable. Also it was odd not to be able to view your whole score at any time, you were forced to remember it until it showed you at the end.
Overall, really nice, has some small issues, but nothing that really gets in the way of having a good time.
